Specific implementation mode
Referring to Fig.1-4, tyre assembly 10 according to the present invention may include tire 12, peristaltic pump component 14 and tyre rim
16.Tire 12 can be installed to wheel rim 16 in the usual way.Tire 12 can have conventional configurations, have from opposite bead area
22、24(Bead area 22 is only shown)Extend to crown or a pair of sidewalls 18,20 of tire tread area 26(Side wall is only shown
18).Tire 12 and wheel rim 16 surround tyre cavity 28 together(Fig. 8).
Such as visible from Fig. 2 and 3, peristaltic pump component 14 may include the annular air pipe 30 for surrounding annular access 32.Pipe 30
It can be formed by elasticity, flexible material, can such as sustain the plastics or rubber composite of the deformation cycle of repetition.Such structure
It makes, pipe 30 can be deformed into flat condition in tire 12 when by external force, and when removing this power, return to initial shape
State.In the example shown, the cross section of the pipe 30 in the state of not stressing can be substantial circular, but replacement can also be used
The geometry of the pipe of property.The diameter of pipe 30 can be enough operatively to pass through the air of required volume, to pump air
Into tyre cavity 28, to keep tire 12 to be in preferred the blowing pressure.
It is had shown and described in United States Patent (USP) No. 8,113,254 and deformable air hose is merged to the wriggling original in tire
Reason, the whole of the patent are incorporated herein by reference.In such a system, pipe, which is incorporated in, is formed in tire close to tire bead
In the annular tire access in region.When tire under loads when rotated, allow the air outside tire to enter in pipe, and with
Tire rotates, and the air is pumped along air hose by the pipe in progressive crush tire.Therefore, outlet valve is forced the air into
In, subsequently into tire, to keep the air pressure in tyre cavity to be in desired stress level.
Pipe 30 can be closely installed in the groove 32 in tire 12, and sequence flattens when tire rotates.Pipe 30
A section connect flattening for section, tire 12 air is pumped into along air flue/groove 32 in tyre cavity 28 with
Keep air pressure.The United States Patent (USP) No. 8,042,586 of mandate shows the peristaltic pump using the pipe 30 in side wall groove 32
System 14, the whole of the patent is sent to be incorporated herein by reference.
With reference to Fig. 3,4 and 9, pump line 30 is generally annular and around close to the lower tire sidewall region of bead area 22
Domain.But the other configurations of pipe 30 can be found out without departing from the present invention.The opposite end 34,36 of pipe 30 is connected to three-way connection
38.The conical pump line port 40,42 blocked can become narrow gradually along the direction far from three-way connection 38, and each port has inside
Axial air access, the air flue provide the air duct into three-way connection 38.As shown in Figure 4, pipe port 40,42
It can inwardly become narrow gradually to distal end, and can be received in the end 34,36 of pipe 30, air hose 30 is connected to three and is connected
First 38.Three-way connection 38 can limit interior chamber.
With reference to Fig. 3 and 4, opposite end 34,36 can be connected on the pipe port 40,42 of three-way connection 38 by pump line 30.
The third port 68 of three-way connection 38 may be connected to the end 72 of elongated connecting tube 70.The opposite end 74 of connecting tube 70 is attached to greatly
The valve chest 101 of body cylinder, valve chest 101 are threadably attached to the valve rod 80 of tire/wheel rim component 12,16.One-way non-return
Valve 76 can be placed in valve rod 80, be opened and closed to allow air to enter in tyre cavity 28 from pipe 30.
The drawing of " opening " state and the air maintenance tire system of " closing " position is shown respectively in Figures 5 and 6, in " opening "
State, air are pumped into tyre cavity 28, and in " closing " position, tire cavity pressure is in aspiration level.Valve chest 101 can be adopted
Use lower end in valve chest or to the check-valves 76 of the valve rod 80 at inner end as adjuster.Valve chest 101 can also have peace
Full valve 105 opens and closes so that pump 14 is in open and close situation.Air can be allowed to enter valve casing
Body 101 and tyre cavity 28 can be directed to from pipe 30.As described above, pipe 30 can be integrated into the groove 32 in sidewall
In(See Fig. 7 and 8), and can by the rotation of tire 12 under loads it is progressive flatten.
With reference to Fig. 4-6 and 9, filled by hand component 200 can be located at the upper end or outer end of valve chest 101.Filled by hand group
Part 200 may include check-valves 202 so that can carry out manual pressure to tyre cavity 28, this is directly added by valve rod 80 manually with same
It presses identical.
Alternatively, air flue 32 can be directly encapsulated in tyre element, pipe 30 be omitted, without departing from the present invention.
In this component(It is not shown)In, when tire 12 rotates under loads, air flue 32 will similarly, and a section connects one
Section, pumped air, and air flue will be directly coupled to three-way connection 38 at opposite end 34,36.
When tire 12 load along ground continue rotation when, pipe 30 can close to tire print when sequence flatten or be squeezed
Pressure.The sequence that one section of the pipe access 32 that Fig. 7 and 8 describes connects a section flattens, and can be waited for what is be discharged from the section that flattens
The air of direction pumping shown in the Figures 5 and 6 is guided to three-way connection 38 and valve chest 101.When air flow pressure is enough to resist
When check-valves 76, air can flow through valve rod 80 and enter tyre cavity 28(Fig. 5).When the air pressure in tyre cavity 28 is less than setting pressure
When, air can be from connecting tube 70 by valve chest 101, into valve rod 80 and tyre cavity.When the air pressure in tyre cavity 28 is equal to
Or when higher than predetermined pressure(Fig. 6), check-valves 76 is closed and air cannot be pumped into from valve chest 101 in valve rod 80.It replaces
Dai Di, forced air can be retained in valve chest 101, until being released to air by safety valve 105.
The check-valves 76 of valve rod 80 and the check-valves 202 of filled by hand component 200 may include conventional valve stem core and spool, valve
Bar core is used for the conventional pneumatic of tire.Spool can be " Schrader Valve Core ", and include valve shaft extend from it is logical
The thin-long casing crossed.Valve seal member can be placed in thin-long casing and be connected in parallel to valve shaft.Bias spring can surround valve shaft, and support
Seal member in thin-long casing is biased in "upper" or " closing " position by anti-valve seal member.Air flue across spool can
It is biased in "Off" state, until valve shaft movement and thus valve seal member is moved to "lower" or " opening " position, by
This acceptable environment air enters air flue and is led to tyre cavity 28.
According to the description of present invention provided herein, the present invention can be changed.Although showing in order to illustrate the present invention
Certain representative embodiments and details are gone out, but it will be apparent to those of ordinary skill in the art that the present invention can have been carried out
Various changes and modifications are without departing from the scope of the present invention.It should therefore be understood that can be carried out to described specific embodiment
Change, these change will be in the range of the complete intention for the present invention being defined by the following claims.
